The embodiment of the invention provides a data processing method and device and a storage medium, and relates to the technical field of the Internet, for solving the problems that an ISV adaptation scheme is complex and high in maintenance cost. The data processing method comprises the following steps: receiving a service request sent by a client, and obtaining a corresponding configuration fileaccording to an ISV identifier and an organization department identifier; obtaining indication information about whether a processing stage in at least one configurable processing stage is executed ornot from the obtained configuration file; and for at least one configurable processing stage, obtaining a dynamic code corresponding to the processing stage from the configuration file, and executinga processing operation corresponding to the processing stage according to the found dynamic code. Thus, since the dynamic code is configured for the configurable processing stage of the service request, when an ISV is newly added, only one configuration needs to be newly added in the configuration file, and the code does not need to be modified, and implementation classes do not need to be added,so that the adaptation difficulty is low, and the maintenance is convenient.
